I am registered in a number of states. North Carolina is Jan1 thru Dec 31, Florida is Feb 28(9) thru Feb 28(9), South Carolina, (I believe ) is Jun 30 thru June 30,  Its inconsistent. You might be ok with some states, but for instance, if I have the required number of CEUs for North Carolina, but took courses in January, these credits go on the previous year in Florida. There is no consistency. This needs to be worked out with all states to gain a uniform time for credits. This boils down to  some instances where I have to take extra courses just to be sure I am covered in all the states I am registered in.
